10+2 (PHYSICS)INSTRUCTIONS FOR PAPER SETTERNote:1. There will be one theory paper consisting of total 26 questions.Three questions of two mark each & three questions of three markseach are choice questions will be set in the paper.2. Question no.6 to 14 will be of 2 marks each, out of total 9 questionscarrying 2 marks each, candidate can attempt any 6 questions.3. Question no.15 to 23 will be of 3 marks each. Out of 9 questions carrying3 marks each, candidate can attempt any 6 questions.4. Question no. 24 to 26 will be of five marks each. There will beinternal choice in them.5. From one unit, only choice question either of two marks of three markscan be set e.g. if in one unit according to marks distribution scheme thereis no three mark question then examiner can select 3 marks choicequestion from that unit, same pattern will be followed for two markschoice question.SYLLABUS : THEORYUnit 1: ElectrostaticsElectric Charges; Conservation of charge, Coulomb's law-force between twopoint charges, forces between multiple charges; superposition principle andcontinuous charge distribution.
